Abstract

A method and apparatus for treating a condition of a patient'"'"'s airway includes identifying a patient with obstructive sleep apnea and identifying a muscle of a tongue of the patient. A first brace is implanted within the tongue at a first implant location near the top of the tongue. A second brace is implanted within the tongue at a second implant location below the upper location. The first and second braces are connected to compress the muscle group.

Claims

1. A method for treating an upper airway condition, said method including:

identifying a patient with obstructive sleep apnea;

identifying a muscle of a tongue of said patient;

implanting a first brace within said tongue at a first implant location at an upper location in said muscle;

implanting a second brace within said tongue at a second implant location spaced below said upper location;

connecting said first and second braces to resist an elongation of a spacing between first and second braces;

wherein said first brace is a plate having a length, width and thickness with said thickness substantially less than either of said length and width, and wherein said method further including;

implanting said first brace in a first implant orientation with said length substantially transverse to an anterior-posterior axis of said tongue and with said width substantially in-line with said axis.

2. A method for treating an upper airway condition, said method including:

identifying a patient with obstructive sleep apnea;

identifying a muscle of a tongue of said patient;

implanting a first brace within said tongue at a first implant location at an upper location in said muscle;

surgically accessing said first implant location by an incision through a mucosal layer said tongue and

placing said first brace in said first implant location and in said alignment beneath said mucosal layer

implanting a second brace within said tongue at a second implant location spaced below said upper location;

connecting said first and second braces to resist an elongation of a spacing between first and second braces;

wherein said muscle includes a genioglossus muscle.

3. A method according to claim 2 wherein said surgical access includes formation of a mucosal flap and placing said first brace beneath said flap.

4. A method for treating an upper airway condition, said method including:

identifying a patient with obstructive sleep apnea;

identifying a muscle of a tongue of said patient;

implanting a first brace within said tongue at a first implant location at an upper location in said muscle;

implanting a second brace within said tongue at a second implant location spaced below said upper location;

connecting said first and second braces to resist an elongation of a spacing between first and second braces;

wherein said second brace is a plate having a length, width and thickness with said thickness substantially less than either of said length and width, and wherein said method further including;

implanting said second brace in a second implant orientation with said length substantially transverse to an anterior-posterior axis of said tongue and with said width substantially in-line with said axis.

5. A method according to claim 4 further comprising:

surgically accessing said second implant location by an incision beneath a chin of said patient; and

placing said second brace in said second implant location and in said alignment beneath said mucosal layer.

6. A method for treating an upper airway condition, said method including:

identifying a patient with obstructive sleep apnea;

forming an upper incision through an upper surface of a tongue of said patient to define a pocket to receive an implant;

selecting a brace member sized to be received within said pocket, said brace member having a lower surface opposing tissue of said tongue;

inserting said brace member into said pocket;

closing said upper incision;

inserting a retaining member through a bottom of said tongue and coupling a first end of said retaining member to said brace member; and

securing a second end of said retaining member to tissue in proximity to said bottom of said tongue;

wherein said brace member is a plate having a length, width and thickness with said thickness substantially less than either of said length and width, said method including;

inserting said brace member in said pocket with an orientation for said length to be substantially transverse to an anterior-posterior axis of said tongue and with said width substantially in-line with said axis.

7. A method according to claim 6 wherein said retaining member includes a longitudinal axis, said inserting of said retaining member includes:

surgically accessing said pocket by a lower incision beneath a chin of said patient and through said bottom of said tongue and defining a surgically created path from said lower incision to said pocket;

orienting said retaining member with said longitudinal axis substantially aligned with said surgical path;

advancing said retaining member in said alignment through said surgically created path to said pocket;

securing said first end to said first brace.

8. A method for treating an upper airway condition, said method including:

identifying a patient with obstructive sleep apnea;

forming an upper incision through an upper surface of a tongue of said patient to define a pocket to receive an implant;

selecting a brace member sized to be received within said pocket, said brace member having a lower surface opposing tissue of said tongue;

inserting said brace member into said pocket;

closing said upper incision;

inserting a retaining member through a bottom of said tongue and coupling a first end of said retaining member to said brace member; and

securing a second end of said retaining member to tissue in proximity to said bottom of said tongue;

wherein said retaining member includes an elongated member terminating at said first end and adapted to be coupled to said brace member, said retaining member further including retention plate at said second end, said securing of said second end including implanting said second end near said bottom of said tongue with said plate resisting migration of said second end toward said upper surface of said tongue.

9. An apparatus for treating obstructive sleep apnea of a patient, said apparatus including:

a first brace dimensioned so as to be implanted at a first implant location within a muscle of a tongue of said patient below a mucosal layer of said tongue;

a retaining member dimensioned so as to be implanted within said tongue at a second implant location below said first implant location; and

a connecting element adapted to connect said first brace and said retaining member to resist an elongation of a spacing between first brace and said retaining member;

said first brace is a plate having a length, width and thickness with said thickness substantially less than either of said length and width;

said length, width and thickness sized for said first brace to be implanting in a first implant orientation with said length substantially transverse to an anterior-posterior axis of said tongue and with said width substantially in-line with said axis.

10. An apparatus for treating obstructive sleep apnea of a patient, said apparatus including:

a first brace dimensioned so as to be implanted at a first implant location within a muscle of a tongue of said patient below a mucosal layer of said tongue;

a retaining member dimensioned so as to be implanted within said tongue at a second implant location below said first implant location; and

a connecting element adapted to connect said first brace and said retaining member to resist an elongation of a spacing between first brace and said retaining member;

said retaining member is a plate having a length, width and thickness with said thickness substantially less than either of said length and width;

said length, width and thickness sized for said retaining member to be implanting in a second implant orientation with said length substantially transverse to an anterior-posterior axis of said tongue and with said width substantially in-line with said axis.

11. An apparatus according to claim 10 wherein said connecting element is adapted to resist elongation.

12. An apparatus according to claim 11 wherein said connecting element has an adjustable length.
